Harris Seeds Vinca Cora Cascade

The F1 designation indicates that these are hybrid seeds, specifically bred by crossing two distinct parent lines. This process is used to combine desirable traits like superior vigor, disease resistance, and consistent bloom size, resulting in a more uniform and reliable plant than open-pollinated varieties.

No, these are raw, untreated seeds. They come in their natural state without any fungicide or chemical coatings applied.

They are specifically bred for containers. Their natural trailing habit and well-branched structure make them excellent for hanging baskets, window boxes, and patio pots where they can spill over the edges, though they will also perform well as a mounded ground cover in garden beds.

Aerial Phytophthora is a common fungal disease that can cause stem blight and leaf spots in vinca, often triggered by humid or wet conditions. This variety's high tolerance means it is significantly less likely to succumb to these infections, helping your plants stay healthy and lush throughout the season.

No, you do not need to pinch them. This variety is naturally well-branched, meaning it will develop a full, spreading habit on its own without extra maintenance.

These plants thrive in full sun. For the best bloom production and to maintain their compact, trailing habit, ensure they receive at least six to eight hours of direct sunlight daily.
